lated thereon, driving the same up the .itat-k 26. Thil accoinplibhetl the lever 1t) is turned y one-quarter ol' a revolution to right or left.

and the steam passes through the tube `1i', or the tube 15, iiecorilingly, and ia-.-in

tlirou fb that one of the `eompiiriment.-; or

cham ers of the header 19 with whieh the tube used is connected, eiiteinl the three depending tubes 10, opening;r from sin-b eomA piirtinent or chamber, and i ejected through the nozzles 2l thereon, and into and tliroiwh the boiler tlues opposite which those nozz es are placed. tleiiring said lli-.es of all deosits of produetsaif eombnstiilii und tlirow lng the same into the space below the rear end of the boiler. At each quarter tarn of the' lever 10 the saine result is etl'ected in three series of boilerv tliies, until all are thoroughly cleaned, when valve 3 is closed to shut olf steam, and vulve 5 opened to drain i tubes and valve 8 into the ash pit.

The nozzles 21, are formed as shown, with miirlginal apertures opening outwardly at an ang o with the axis of the nozzle, und the central a erture of the nozzle 'is ritled to pro)ect tie steam against the entire inner side of each boiler flue, and to give it a wyliirlin motion, calculated to more etlic'iently c ear the tubes of all looe deposits.

Hitting thus described my invention, l claim: l

l.. The combination of a boiler, and' means for simultaneously driving a pluralit tions of lies and tlie like. l

2. In boiler cleaning apparatus, thi comof jets, of steam orer the upper surface o the f shell of sind boiler, to clear it ofaeciimiilu- Intuition of a team duet located in por; or. the top of the shell of a boiler, and iiiiiinif :i lateral extension provided with aperture. o ieninp; therefrom with their axes mii-'tow tnilly parallel with the top of said boiler shell. and a controlling valve for regnlnti'e I the llow offteam through said duet and Iaieral extension. i 2l. ln boiler leaning apparatus, thtl um:

bination of a main `team duet loeateil on the upper iart of the shell of a boiler, :ont extending ongitmlinally thereof, a .-erieof l lateral bra-liebes of said steam duet, eavh ol aii'l branche having a plurality of :iperl tures opening toward one end of the hoiiei. :and contiguous to the shell thereof, anti means for eontrollin i'tliiou'h said main hriine ies.

4. ln boiler cleaning apparatus, the combiniition of a niain steam duct; a plurality of secondary ducts directed respeetii ely to uct and Said lateral the upper portion of the shell of a boiler. a
